Junos MPLS and VPNs (JMV)

( Duration: 5 Days )

The Juniper Junos MPLS and VPNS (JMV) Training course is designed to provide Participants with MPLS-based virtual private network (VPN) knowledge and configuration examples. The course includes an overview of MPLS concepts such as control and forwarding plane, RSVP Traffic Engineering, LDP, Layer 3 VPNs, next-generation multicast virtual private networks (MVPNs), BGP Layer 2 VPNs, LDP Layer 2 Circuits, and virtual private LAN service (VPLS).
